Overview
The L4995AJTR is a part of the L4995 family of monolithic integrated 5 V voltage regulators produced by STMicroelectronics. This device is designed to provide a stable 5 V output with a low drop voltage, capable of handling currents up to 500 mA. It is available in both 12 and 24 pin packages, specifically the PowerSSO 12 package for the L4995AJTR model. The regulator features a p-channel MOS output voltage regulating element and is robust against input voltage transients up to 40 V. It is particularly suited for automotive applications due to its high precision output voltage and comprehensive protection features.
